SPECIFICATION forming part of Letters Iatent No. 543,925, dated August6, 1895.

Application filed January 9, 1895.. Serial No. 534,334. (No model.)

To all whom it may concern:

Be it known that I, FREDERICK L; Cons, 'a citizen of the United States,residing at Worcester, in the county of Worcester and State ofMassachusetts, have invented anew and useful Improvement in Wrenches, ofwhich the following, together with the accompanying drawings, is aspecification sufficiently full, clear, and exact to enable per- 1: sonsskilled in the art to which this invention'appertains to make and usethe same.

This invention relates to the peculiar construction and manner ofcombining the Wrench-bar and handle by means of trans- 5versely-disposedinterlocking keys introduced and upset into oppositerecesses or grooves formed across the sides of the wrench-bar and withinthe body of the ferrule, as more fully hereinafter explained, the objectof my invention being to afford a simple, inexpensive, and rigidlystrong construction in a wrench or tool of the class, as specified.

In the drawings, Figure 1 is a side view of a wrench embodying myinvention. is a transverse section at line W W. Fig. 3 is a transversesection at line Y Y. Fig. 4 is a longitudinal section at line X X. Fig.5 is a side view of the bar-shank, and Fig. 6 shows the form of theinterlocking key.

. Referring to parts, A denotes the Wrench- .bar; A, the fixed jaw; B,the movable jaw; C, the rosette screw; D, the ferrule; E, the woodhandle, and F the tip or end piece.

According to my present invention the bar- 3 5 shank A is made with thatportion whichis within the ferrule formed with fiat parallel sides a androunded front and rear edges a below the shoulder h. A groove G is cutor formed in the fiat side a of the bar-shank, extending transverselyacross the same, and prescnting a square shoulder i at-its lowerlimit.The interior opening through the ferrule D is shaped to fit the flatsides and rounded edges of the shank. A transverse groove cl is formedin the inner surface of the ferrule,

tend as rectangular openings through thebody of the ferrule at positionssomewhat be- Fig. 2

low the rosette-steps D or as indicated at m.

The grooves in the bar-shank are preferably made somewhat Wider than thegrooves in the ferrule, as shown.

When the parts are assembled, a rectangu lar key K, the width of whichcorresponds with the width of the groove in the ferrule and of athickness equal to the depth of the grooves in both the ferrule andbar-shank 6e and of sufficient length to reach through the ferrule, isintroduced or driven into the opening m and grooves cl and G, which key,seating on the shoulders t', n, and i, interlocks with both thebar-shank'and ferrule and holds the ferrule securely in place upon thebar-shank with its end firmly against the shoulder h. The key. isupsetand wedged firmly within the groove-space and against the shouldersi, t", and it by riveting down its ends m, which ends are subsequentlydressed off flush and smooth with the exterior surface of the ferrule,thus producing a solid and finished connection for the parts.

The wood hand piece E, which is best formed in a single piece, has alongitudinal opening 0, oblong in cross-section, extending therethroughfor receiving the bar-shank, the respective ends of the hand-piece beingreduced and inserted beneath the lips e e formed on the ferrule D andtip F, as shown, and the tip being arranged upon the reduced end a ofthe shank, which latter is riveted into the opening of the tip atf inwell-known manner. 8

I claim and desire to secure by Letters Patent 1. The wrench-bar-shankhaving the transverse groove formed in the flat side thereof, with asquare seating shoulder at the lower limit of said groove; incombination, with the ferrule having an opposite internal transversegroove, of less width, with seating shoulders at its upper and'lowerlimit, and openings at the ends of such groove through the body of 5 theferrule, and the angular interlocking-key fitting the width of saidferrule groove, upset within the opposite grooves and against the lowerseating shoulders of both the bar-shank and ferrule, for the purpose setforth.

2. The wrench-handle composed of the ferrule, its interior fitting uponthe bar-shank,

and having transverse internal grooves and bar-shank, said keys upsetwithin the groove shoulders with openings at the ends of said spacesfirmly against the shoulders, their ends grooves through the body of theferrule, the riveted and dressed off flush with the cxter 5 end-tipattached to the shank end and the rior surface of the ferrule,substantially as 5 hand piece having a transversely oblong opensetforth.
